但是……

当我尝试通过从命令行运行 gradlew 来进一步调查时，没有报告错误。

./gradlew :app:assembleDebug

Deprecated Gradle features were used in this build, making it incompatible with Gradle 6.0.
Use '--warning-mode all' to show the individual deprecation warnings.

所以我不知道如何进行。这是一个商业媒体应用程序，已经通过了 beta 测试，本来应该发布的……但现在这让我受阻了。

到目前为止我尝试过的事情......

清理并重建 文件 -> 使缓存无效并重新启动 擦除项目 .gradle 和 user/.gradle 缓存，清理并重建 在 gradle.config 中启用MultiDex = true 将 JVM 内存从 2MB 增加到 4MB 重新启动计算机

问题

如何解决此异常并摆脱困境？ 是我的代码还是 R8 错误？ 为什么我不能从命令行重现错误？ Android Studio 是否在运行带有额外标志的 gradle 时未报告？

【问题讨论】：

第二天重新启动后，发现buildTools可以更新到29.0.2。然后问题就消失了。

即使在更新 buildTools 后也面临同样的问题

【参考方案1】：

遵循commit 38934 中提到的解决方法并禁用高级分析

【参考方案2】：

由于我无权发表评论，因此发布为答案：

如果您仅在构建到 Lollipop 或 Marshmallow 设备时才看到 R8 Nullpointerexception，那么禁用高级分析对我来说就可以了。

所有功劳归功于安东尼奥姆林！谢谢！

【讨论】：

在这里找到它：运行 -> 编辑配置 -> 分析 -> 启用高级分析

【参考方案3】：

我遇到了类似的问题，就我而言，我通过将 java 版本从 15 降级到 11（Android Studio 包中的默认 java）解决了这个问题

希望这些信息可以帮助像我一样遇到同样情况的人?
